New Graphical Representation of the Periodic Table
KentuckyFC writes "The great power of Mendeleev's periodic table was that it allowed him to predict the properties of undiscovered elements. But can this arrangement be improved? Two new envisionings of the periodic table attempt to do just that. The first uses a new graphical representation that shows the relative sizes of atoms as well as their groups and periods. The other uses the same kind of group theoretical approach that particle physicists developed to classify particles by their symmetries (abstract). That helped particle physicists predict the existence of new particles, but may have limited utility for chemists who seem to have discovered (or predicted) all of the elements they need already."
looks like something that should be on a game show. "I'll take Silicon for 500!"
but that design doesn't look much better than the current one. In fact, it looks worse. Helium and Hydrogen overlap, and part of the table is cut off completely. Some might whine that part of the table is cut off in the current version too, but that's just to make it fit on a page, it actually is one contiguous body.
I believe the age-old axiom "If it isn't broken, don't fix it" applies here.

Is not strange the color scheme... you can see clearly now the Blue Elements of Death
If you're gonna go and change it, why not make it correct while you're at it?
Teach the controversy, people!
Unfortunately, Abubakr's arrangement means that the table can only be read by rotating it. That's tricky with a textbook and impossible with most computer screens.
Please, can somebody find a solution to this important screen rotation problem?
To quote a history book (pp. 20-21):
10 PRINT CHR$(205.5+RND(1)); : GOTO 10
The atomic radii don't progress in a nice orderly linear increase in size with increasing element number; in fact each period overlaps part of the period that comes before it...
The atom size thing is no more present in the circular table than in the normal table. If distance from the center correlates with size, then Li and Ne are the same size according to the circular table. Lithium is about twice as big.
As for the H/He placement, helium is a noble gas, there is no question about that.
The circle table also mucks up the order of filling. Why are neon and lithium next to each other?

Another periodic table, is not news.
Someone should have already linked one of the periodic table databases like:

Often wrong but never in doubt.

Everyone knows me.
The new table that came out of Microsoft Research just seems silly. The idea that "closer to the middle means smaller atoms" is a new contribution seems bogus - with the traditional table, closer to the top means smaller atoms. Really the only advantage I can see is the separation of hydrogen and helium away from the other atom groups, which is something that could be easily accomplished using the current table. The circular design itself is a BIG disadvantage.
The second table seems like a more interesting concept. I tried making it through the actual paper - while it sounds like the author thinks the information conveyed in his redesign are better than in the current layout, I didn't see that it actually conveyed new information.
Disclaimer: I have done grad work in physics; but that was almost 20 years ago, and I don't work in anything even close to the field anymore.

Yeah, but remeber, it's from Microsoft Research. They're innovators, dammit!
Not only have the patented the round table, they've also patented the time machine they're going to use to back in time and sue Erdmann and Mendeleev.
And then King Arthur.

Concentric circles don't show that any better than rows do. What rows do better is clearly indicate that the shells get filled in a certain order (left to right). Looking at the circle table, which has more electrons, Li or Ne? F or Ne? Is that intuitive or better?

intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
That said, though, jogging one's memory isn't the best use of a table; given one put in front of you it'd be nice if its organization alone gave you information. I suppose that the circular representation could do this, with perhaps a few labels.
Of course this circular representation isn't all that new; the Chemical Galaxy has been around for a number of years now and has a similar structure.
Oh, here's a link I just found to the chart http://www.meta-synthesis.com/webbook/35_pt/pt_database.php?PT_id=164

The really interesting table on that site is this one: ... Did Mohd rip off Wikipedia?
http://www.meta-synthesis.com/webbook/35_pt/pt_database.php?PT_id=35
Which is labeled "Wikipedia table" and dated 2006
Fortunately for him, wikipedia's history traces back to this revision which was apparently made by Mohd Abubuakr himself, back in August 2006. He was in school at the time, at Jawaharlal Nehru Tech. According to his LinkedIn profile, he's not so much a green field researcher as he is a techie ... Performance and Security consulting. The article is a little misleading ... makes it sound like MS research has a skunk works in Hyderabad trying to invent a new periodic table.
His blog is cute too. A little emo, a little egotistical, but seems like a nice guy. I wonder what his /. handle is.
